HAROLD B... WARNER AND BERTIE RAILSON, OF SEATTLE; WASHINGTON.

-v COMBINED aonLrm AND BALL BEARING.

To all whom it may concern:

Be it known that we, HAROLD R. VV RNEI: and Bnn'rrn 1 RAILSON, citizens of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Combined Roller and Ball Bearings, of which the following is a specilication.

This invention relates to roller and ball bearings for vehicles. Axles of vehicles should be tough to resist jolting strains, and hard to resist wear under heavy loads.

The-object of this invention is'to interpose between the 'wheel and an axle which is soft enough to be tough, hard roller and ball bearings.

.To this end'our invention consists in the construction and combination of parts forming a combined roller and ball bearing hereinal'ter more fully described and particle la rl v stated in the claim, reference being bad to the accompanying drawing in which- Figure 1, shows in longitudinal section a combinedroller and ball bearing according to our invention, adjacent portions of a wheel and axle not shaded. Fig. 2, shows a vertical section at line 02, Fig. 1. Fig. 3, shows in side view a segment of the ballcarrying web. Fig. 4, is an opposite face view of the segment shown in Fig. 3. Fig. 5 is a section view of a fragment at line 7 Fig. 4. v

l'ict numeral 4 represent a vehicle axle with a shoulder a washer 6 and a screw nut 7: and the hub of a wheel having side co.iars and 10. sleeve ll, shaped with flaring shoulders l2,-is titted upon the axle.

A bushing 13. having an inwardlyproject-,

ing flange ll, isflitted closely into the \vheel hub H and is retaiiwd therein' hy collars 9, l0. llollers'lii, mounted on shal't pins 16 that are rigidly fixed in side rings' '17. roll upon the sleeve 11. and within the bushing 1 collar 19, is screwtln'eaded at 1!) into the bushing and is grooved to form a circular path for balls 20, that are n'iounted in a spacing ring 21 to roll against one ol the shoulders l2, of the sleeve ll. Another set of balls 22,.are mounted in a spacing ring 2?), to roll in a groove ll. ltoles are drilled in each of these rings leaving an inwardly projecting flange 24, at one side, and having prongs 25 projecting"inward to TGEaIn the Specification of Letters Patent.

balls. Each ring 2123, is a little thinner than the diameter of a ball 20-22, leaving the balls to project at both sides, and the prongs 25, are formed by driving a coldchisel into the face of the ring and raising the prong to be afterward bent over the ball. In operation, thewheel hub with its bushing 13, hears upon the rollers '15, and they roll upon the sleeve 11, thus supporting the weight of the vehicle, and the balls between the shoulders 12, and flange M, and collar 18 resist endwise thrust of the wheel on the axle. The rings 17, also bear against the balls if they move endwise relatively to the axle. After the collar ;18, has been screwed into the bushing 13, to properly ad- I just the ball bearings, it may be so bound by pressure of the hub collar 10. By means of nut 7,. and washer (3,the sleeve 11,'is rigidly bound against tl e shoulder 5. By removing the out 7 the hole wheel, includ- 7 5 'ing our hearing, may he slipped off from the axle, so that it may he turned nipoiYeit-her face to examine or adjust the parts; and the sleevell. or, any other part may be readily replaced it it should become broken or worn.
